An actual real-world user of ES6 Map (in Firefox-only code) is asking for a .clear() method: <jcranmer> I'm writing a mork reader in JS for mconley's new addressbook (using JS workers, OS.File, and JS Maps !) <jcranmer> one of the operations I need to be able to do amounts to "clear the entire table" <jcranmer> I can't just make it a new map, since I put other properties on the map that I don't want to lose <jcranmer> I'm doing this for now: <jcranmer> for (let [tid, value] of this._currentTable) <jcranmer> this._currentTable.delete(tid); <jorendorff> why store those extra properties on this._currentTable rather than directly on this? <jcranmer> because I have multiple tables In our current implementation, a builtin Map.prototype.clear method that simply removes all entries from the Map would be quite a bit faster than what jcranmer is currently doing. -j _______________________________________________ es-discuss mailing list [email protected] https://mail.mozilla.org/listinfo/es-discuss
